That's the combination I used successfully in the past: BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM201109=y BR2_PACKAGE_GPU_VIV_BIN_MX6Q=y BR2_PACKAGE_QT5BASE_LINUXFB=y BR2_PACKAGE_QT5BASE_DIRECTFB=y This was with an old buildroot however (2012.08 with a lot of additional patches). > - If I use the last buildroot linaro toolchain 4.8-2013.09, the system > not start because the kernel is to old ( 3.0.35 ). > - If I use the toolchain linaro-4.7-2013.01 the Qt5 qmlscene exit without > message and gpu-viv-bin-mx6q examples not start with the message program > not found. I think that gpu-viv-bin-mx6q are softfp libraries, so they won't work with Linaro (hardfp) toolchains. I'm surprised that qt5 builds at all in that case...
